TS Optics Photoline 3" 1.0x Apo flattener and field corrector


Teleskop-Service has reworked and improved the legendary 3" flattener. The result is an outstanding field corrector for astrophotography with large sensors, like full-frame size cameras. The typical field aberrations of refractors, like astigmatism and field curvature, are optimally corrected here.

Distance recommendations


The corrector is optimized for refractors of at least 700 mm focal length, but it can also be used with refractors of shorter focal length. The refractor has to offer a backfocus of at least 150 mm from the connection thread.

If it is used together with the M48 adapter, the following distances will result:

• 
  Refractors of at least 700 mm focal length: 55 mm from the M48 thread
• 
  Refractors from 480 mm to 690 mm focal length: 60 mm from the M48 thread
• 
  The corrector is not suitable for refractors with a shorter focal length.

From the M80x1 connection thread, you have the following generous working distances:

• 
  Refractors of at least 700 mm focal length: 116 mm
  
• 
  Refractors from 480 mm to 690 mm focal length: 121 mm
  

Adapting to your telescope


The corrector requires at least a 2.5" focuser. At the telescope side, a male M92x1 thread is at your disposal.

Individual camera adaption from the male M80x1 thread


If you unscrew the M48 camera adapter, a male M80x1 thread is at your disposal. We offer adapters to all popular threads, like M68x1 Zeiss style, M48x0.75, SC. … Thus you can configure your own individual adaption and adapt accessories like off-axis guiders or filter wheels.
